Question

Does the table of values represent a function? Why or why not?

A.No, it's not a function because the x value 5 has multiple outputs

B. No, it's not a function because the x value 2 is repeated

C. Yes, its a function because there are not variables for missing numbers

Answer 1

A
The input 5 has two different outputs so this is not a function. For it to be a function each input must have just one output.
